I got no problem with fetishes. Druggies can have their fun so long as it hurts no one, Blood and gore? Kinda inevitable sooner or later. Art theft....well, I'd have voted for that too if we could make multiple votes, because the reason is obvious.
Thus my vote was decided by coin flip, and wound up with Hate Art.
Perhaps I have thick skin... or perhaps I tend to be a bit more adult when it comes to art; Nothing on this lists bothers me aside from Art theft. Though you forgot to mention the scat/piss fetishes... I've seen plenty of that on DA.
This is true. DA has some pretty nasty ones on here, but there are some that really don't bother me. People have fetishes, it's never going to go away, and the best action is just do your best to ignore it.
What shouldn't be ignored however is art theft. That's more than just showing off your privates to people who you'll never meet in your whole life; that's downright wrong and takes people's incomes.
I'm sort of surprised what works and doesn't work for people. The leading categories so far are very people specific (and sort of dA interaction specific) rather than general taste in "art", minus the hate art thing you personally referenced. I haven't figure why that's losing to booze.
